Can You Use Fuses from an XP-630 Mainboard to Replace the F1 Fuse on an Epson XP-15000?

Question:

I accidentally blew the F1 fuse on my Epson XP-15000 printer. I have an old XP-630 mainboard lying around, but it also has a blown F1 fuse and doesn’t seem to have an F2 or F3. Can I salvage any remaining fuses from the XP-630 board to replace the F1 on the XP-15000?

Answer:

Understanding Fuse Layout and Compatibility

From our experience working with these boards, Epson typically consolidates all board fuses into one area. If you find one fuse, the others—if they exist—will likely be grouped nearby. The XP-630 mainboard is exceptionally minimalistic in this regard. It’s designed with only one main surface-mount fuse (F1), and lacks additional fuses like F2 or F3. So, if F1 is blown on the XP-630, and no other fuses are visible, there are no additional usable components on that board to transfer.

Additionally, fuses are rated not just by physical size but also by amperage, voltage tolerance, and response speed (fast-blow vs. slow-blow). Using a fuse from a different board—even if it appears physically compatible—can introduce serious risks. An incorrect rating might cause incomplete circuit protection, possibly damaging other sensitive components such as stepper drivers, microcontrollers, or power regulation circuits.

What Should You Do Instead?

If the F1 on your XP-15000 is blown, your best course of action is to:

• Check the fuse specs: On most Epson boards, the F1 is a surface-mount fuse, usually labeled with its amperage rating (e.g., “2A”, “3A”). You can search for a replacement using this rating, preferably matching the original fuse's size and characteristics.

• Replace with a new surface-mount fuse: Electronic component suppliers like Digi-Key, Mouser, or even Amazon often stock these if you search by part number and rating.

• Double-check for shorts: Fuses blow for a reason. Before replacing it, inspect the board for any short circuits or burnt components to avoid blowing the new fuse again.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we cannot provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis. So, it might take a few weeks to get your printer to drop it off. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed. However, we acknowledge that our rates aren't the most economical. Thus, we highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage (https://youtube.com/@bchtechnologies). Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.
